Technical Field

The present invention relates to the field of computer technologies, and in particular, to a display switching method and an electronic device.

Background

Currently, wearable electronic devices such as smartwatches are typically equipped with conventional displays such as Liquid Crystal Displays (LCDs), organic electroluminescent displays, Organic Light Emitting Diode (OLED) displays, and the like. However, due to limitations in the size of wearable electronic devices such as smartwatches themselves, conventional displays are typically provided with small display areas that display limited information.

For this reason, it is desirable to provide an electronic device and a display switching method thereof capable of providing an image or video display of a larger size and a higher resolution without being limited by the size of a wearable electronic device itself such as a smart watch.

Detailed Description

Various embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Here, it is to be noted that, in the drawings, the same reference numerals are given to constituent parts having substantially the same or similar structures and functions, and repeated description thereof will be omitted.

As described in the background art, the conventional display provided with the wearable electronic device is generally small in display area and can display limited information due to the limitation of the size of the wearable electronic device itself, so that the following problems are caused in use:

1. limited display content

Because of portability, wearable electronic devices (especially, wrist devices) are much smaller than other electronic devices (such as mobile phones, etc.), which inevitably results in limited content displayed in the display interface and no way of displaying richer and more specific information, as in electronic devices equipped with large screens.

2. Is troublesome to operate

The wearable electronic equipment has the function that a user can process personal things (such as searching contacts, reading short messages, viewing pictures and the like) at any time. However, since there is only a display interface with a small screen thereon, many frequent operations may be required to complete reading and entry of a content with a large amount of information.

3. Inconvenience in obtaining key information

Since a user tends not to be constantly in a state of concentrating on obtaining information while using the wearable electronic device, and since content that originally needs to be presented in a large screen tends to have a large amount of information, it tends not to be convenient for the user to quickly and conveniently obtain key information when it is directly presented on a small screen of the wearable electronic device.

In view of the first problem described above, in the related art, the display screen of the wearable electronic device can be enlarged as much as possible. However, this inevitably makes the wearable electronic device bulky, and in consideration of convenience when worn on the body of the user, even the size of the expanded display screen is limited.

In view of the second problem, the operation mode and the man-machine interaction interface of the wearable electronic device can be modified in the prior art. However, there is still no way to substantially increase the convenience of obtaining information by a user.

In view of the third problem mentioned above, there is no good solution in the prior art for a while

In this regard, in an embodiment of the present invention, there is provided an electronic device and a display switching method thereof capable of providing an image or video display of a larger size and a higher resolution without being limited by the size of a wearable electronic device itself such as a smart watch. Further, the content displayed in the electronic device can be automatically judged and switched according to the distance of the user viewing distance.

Hereinafter, an electronic apparatus according to an embodiment of the present invention will be described first with reference to fig. 1.

From a functional perspective, as illustrated in fig. 1, an electronic device 100 according to an embodiment of the present invention may include: a functional main body 130. The function main body part 130 may be a circuit part for performing various operation functions (e.g., displaying information, generating sound, capturing an image, etc.) in the electronic device.

Specifically, the functional body part 130 may include: a processing device 103, a first display device 104, a second display device 105, and a sensing device 106.

Obviously, the constituent parts of the functional main body portion are not limited thereto. For example, the functional main body part 130 may further include: power supply means (e.g., a battery unit), image capturing means (e.g., a camera), sound reproducing means (e.g., a speaker), and the like, which are not shown.

Among the functional main body section 130, the processing device 103 is used to generate a display image to be displayed and perform display control.

For example, the processing device 103 may include a Central Processing Unit (CPU), Micro Processing Unit (MPU), Digital Signal Processor (DSP), Field Programmable Gate Array (FPGA), Application Specific Integrated Circuit (ASIC), and/or other chip with processing capability, and so on.

The first display means 104 has a first display output area and is arranged to present a first image in a first display effect in the first display output area. More specifically, the first display device 104 may output the first image generated by the processing device 103 under display control performed by the processing device 103. For example, the first image may be any type of display data including, but not limited to: images, videos, text, and even more generally, a graphical user interface of an application, or a standby screen (or referred to as a home interface) of the electronic device 100, or the like. In addition, the first display device 104 may be a display device following various display principles, and the first display effect depends on the display principle of the first display device 104.

Similarly, the second display device 105 has a second display output area and is configured to present a second image in the second display output area with a second display effect. More specifically, the second display device 105 may output the second image generated by the processing device 103 under display control performed by the processing device 103. For example, the second image may be any type of display data including, but not limited to: images, videos, text, and even more generally, a graphical user interface of an application, or a standby screen (or referred to as a home interface) of the electronic device 100, or the like. In addition, the second display device 105 may be a display device following various display principles, and the second display effect depends on the display principle of the second display device 105.

The sensing device 106 is used for obtaining parameter information related to input operations performed by the viewer. For example, the parameter information is used to characterize the input operation of the viewer for the electronic device 100.

In particular, the sensing device 106 may be a sensor that follows various acquisition principles. For example, the sensing device 106 may include, but is not limited to, a gyroscope, a gravity sensor, a proximity sensor, a pressure sensor, a touch sensor, and/or other sensors capable of detecting the spatial position (e.g., an image capturing device, a sound capturing device, a biometric capturing device, etc.) for collecting various parameter information of the same or different types to determine whether the input operation of the electronic apparatus 100 by the viewer satisfies a predetermined condition.

From a structural point of view, the electronic device 100 according to an embodiment of the present invention may be any electronic device including the above-described apparatus. For example, it may be a wearable electronic device or any other type of electronic device.

In the case where the electronic device 100 is a wearable electronic device, it may include: the electronic device comprises a frame body, a fixing device and a functional main body part, wherein the fixing device is connected with the frame body and is used for fixing the relative position relation of a user of the electronic device 100.

Further, in the case that the electronic device 100 is a head-mounted electronic device, the fixing device may have a corresponding supporting member according to a form of the head-mounted electronic device (for example, the head-mounted electronic device is smart glasses or a head-mounted display). For example, in the case of smart glasses, the fixing means are two support members (i.e., temples and nose bridge supports) connected at both ends of the smart glasses or three support members (i.e., temples, lens frames and nose bridge supports) at both ends and in the middle of the smart glasses, so that the eye legs located at both ends of the space and the nose bridge support located in the middle of the space form an approximately rectangular space for enclosing the head of the person. When a user configures the head-mounted electronic device, the display output area of the display device is arranged in the eye area of the user, so that the emergent direction of the display device faces the eyes of the user. Furthermore, the electronic device 100 may also be a wrist-worn electronic device (e.g., in a watch configuration) or a finger-worn electronic device (e.g., in a ring configuration).

Hereinafter, an application scenario of the wrist-worn electronic device will be described in further detail in one specific example with reference to fig. 2.

As illustrated in fig. 2, in a specific example, the electronic device 100 may be a wrist-worn electronic device including a frame body 110, a fixing device 120, and a functional body portion 130.

The fixing device 120 is connected with the frame body 110, and is used to fix the electronic apparatus on a first manipulation body (e.g., a head, an arm, a finger, etc.) of a viewer (e.g., a user).

Specifically, the fixture 120 includes at least a fixed state in which the fixture 120 can be at least a portion of an annulus or an approximate annulus that satisfies a first shape condition, the annulus or the approximate annulus surrounding a cylinder that satisfies a second shape condition.

Hereinafter, the first configuration example to the fourth configuration example of the fixture will be described further with reference to fig. 3A to 3D. In fig. 3A to 3D, only the frame body 110 and the fixing device 120 in the electronic apparatus 100 are shown for simplicity and clarity of description.

Specifically, fig. 3A and 3B illustrate two fixing states in which the fixing device 120 is connected to the frame body 110, respectively. In a first fixing state as shown in fig. 3A, the fixing device 120 and the frame body 110 form a closed annular space, wherein the fixing device 120 and the frame body 110 respectively form a part of the annular space. In the second fixing state as shown in fig. 3B, the fixing device 120 and the frame body 110 form an approximately annular space with a small opening, wherein the fixing device 120 and the frame body 110 respectively constitute a part of the annular space. In a preferred embodiment of the present invention, the frame body 110 is a dial portion of a smart watch, and the fixing device 120 is a band portion of the smart watch. The annular space or the approximate annular space formed by the frame body 110 and the fixing device 120 can surround the wrist of the user of the smart watch as the cylindrical body, and the diameter of the annular space or the approximate annular space is larger than the diameter of the wrist of the user and smaller than the diameter of the fist of the user.

In addition, fig. 3C and 3D illustrate another two fixing states in which the fixing device 120 is coupled to the frame body 110, respectively. The annular space or the approximately annular space may of course also be formed by the fixing means 120 alone. As shown in fig. 3C and 3D, the frame body 110 may be disposed on the fixture 120 (i.e., the frame body 110 is attached to the fixture 120 in a surface contact manner), so that only the fixture 120 itself forms the annular space (fig. 3C) or the approximate annular space (fig. 3D) for externally surrounding the columnar body. The fixing means 120 is arranged with a fixing mechanism (not shown) such as a buckle, a snap, a zipper, etc.

Referring back to fig. 2, other configurations of electronic device 100 are further described.

Since the functional main body part 130 is a circuit part for performing various operation functions (e.g., displaying information, generating sound, capturing an image, etc.) in the electronic apparatus, in order to secure safety and stability thereof, the functional main body part 130 may be provided at the frame body 110 and the fixing device 120 having a certain supporting strength.

In one example, all of the functional modules in the functional main body part 130 may be disposed inside the frame body 110. For example, the processing device 103, the first display device 104, the second display device 105, and the sensing device 106, and other additional units may all be arranged inside the frame body 110.

In another example, in order to save the thickness and area of the body as the wearable electronic device provided in the embodiment of the present invention, at least a part of the functional modules in the functional main body part 130 may be disposed inside the frame body 110, while the rest of the functional modules in the functional main body part 130 may be disposed inside the fixing device 120. For example, as illustrated in fig. 2, the first display device 104, the second display device 105, and the sensing device 106 may be disposed inside the frame body 110, and the processing device 103, and other additional units may be disposed inside the fixing device 120. Alternatively, some functional components of one device may be arranged inside the frame body 110, while the remaining functional components are arranged on the fixing device 120. For example, the display output region of the display device may be disposed on one surface of the frame body 110, but the optical devices inside the display device are disposed in the fixing device 120.

In still another example, all the functional modules in the functional main body 130 may be disposed inside the fixing device 120.

Next, different configurations of the first display device 104 and the second display device 105 will be described in detail.

In order for a viewer to view a first image, the first display device 104 may include a first display output region 1041, the first display output region 1041 being a portion of the first display device 104 that is viewed by a user to perceive display content. That is, the first display device 104 includes a plurality of components depending on its principle as described below, and the first display output region 1041 is a region where the display of image content is actually observed by the user. At this time, the position of the first display device 104 described above may actually refer to the position of the first display output region 1041.

Similarly, for the viewer to view the second image, the second display device 105 may include a second display output region 1051, the second display output region 1051 being the portion of the second display device 105 that is viewed by the user to perceive the display content. That is, the second display apparatus 105 includes a plurality of components depending on its principle, and the second display output region 1051 is a region where display of image content is actually observed by a user. At this time, the position of the second display device 105 described above may actually refer to the position of the second display output area 1051.

In one example, the first display device 104 and the second display device 105 may be identical display devices. For example, the first display device 104 and the second display device 105 may refer to the same display device. In this case, the first display output region 1041 and the second display output region 1051 are the same display output region.

In another example, the first display device 104 and the second display device 105 may be two logical parts obtained by dividing the same physical display device in display function. In this case, the first display output region 1041 and the second display output region 1051 are different display output regions. For example, an LCD display may be scaled from the display screen.

In yet another example, for example, as illustrated in fig. 2, the first display device 104 and the second display device 105 may also be two different display devices. In this case, the first display output region 1041 and the second display output region 1051 are two different display output regions corresponding to each of them.

Specifically, in one embodiment, the first display device 104 and the second display device 105 may be two physical display devices that follow the same display principle.

Alternatively, the first display device 104 and the second display device 105 may be display devices that follow different display principles. That is, the first display device 104 is a different type of display device from the second display device 105.

For example, the first display device 104 may be a general optical display system including, but not limited to, a liquid crystal display device, an organic electroluminescent display device, an organic light emitting diode display device, an E Ink type display device, and the like. At this time, the first display device 104 may present the first image in the first display output region 1041 according to the display effect of the real image.

Meanwhile, the second display device 105 may be a near-eye optical display system. At this time, the second display device 105 may present the second image in the second display output region 1051 with a display effect of a virtual image, that is, the second display device 105 is configured to output a virtual image corresponding to the second image.

As illustrated in fig. 4, the second display device 105 may include: a second display assembly 10 and a second optical assembly 20.

The second display assembly 10 is used to output an initial light ray (e.g., a light ray indicated by a solid arrow in fig. 4) corresponding to the second image.

The second optical component 20, also called a second optical path conversion component, is configured to receive initial light from the second display component 10 corresponding to the second image and perform optical path conversion on the initial light to form a virtual image corresponding to the second image, so that a viewer 30 at a specific position of the electronic device 100 can perceive the virtual image, where the perceived size of the virtual image is larger than that of the second display component 20.

Specifically, in a preferred embodiment of the present invention, the second display assembly 10 may be a self-luminous type display assembly such as an Organic Light Emitting Diode (OLED) display, and may also be a backlight type display assembly such as a liquid crystal display. The second optical member 20 may be a flexible waveguide or the like including a lens group for collimating and magnifying an image and a waveguide sheet for changing an exit direction of the image. Further, the viewer 30 located at a specific position may perceive a virtual image corresponding to the second image. Specifically, images may be imaged by the second optical assembly 20 to specific locations as desired by design, for example, as illustrated in fig. 4, the specific locations may be either side relative to the second optical assembly 20.

Therefore, the second display device 105 according to the embodiment of the present invention as illustrated in fig. 4 may not be limited by the size of the electronic apparatus itself configured with the second display device 105, thereby being capable of providing a larger-sized and higher-resolution image or video display to a viewer located at a specific position according to design needs.

Hereinafter, different configuration examples of the first display output region and the second display output region will be described with reference to fig. 5A to 5F based on the above-described embodiment in which the first display device 104 is a normal display and the second display device 105 is a near-eye display.

Fig. 5A and 5B are a top view and a side view, respectively, illustrating a first configuration example of a display output area of an electronic apparatus according to an embodiment of the present invention.

As shown in fig. 5A, the first display output region 1041 and the second display output region 1051 have a first configuration example of being overlapped on the frame body 110. The present invention is not limited thereto, and the first display output region 1041 and the second display output region 1051 may be overlapped on the fixing device 120.

Fig. 5B further illustrates a side view of a first example of a configuration in which the first display output region 1041 and the second display output region 1051 have an overlapping arrangement. As shown in fig. 5B, the first display device 104 provided with the first display output area 1041 and the second display device 105 provided with the second display output area 1051. As shown in fig. 5B, the first display output region 1041 and the second display output region 1051 are configured such that at least one of the display output regions outside the annular space or the approximate annular space satisfies a predetermined condition of light transmittance in a direction outward from the annular space or the approximate annular space. The predetermined condition may be that the light transmittance is equal to or greater than a predetermined value (such as 70%). In the example shown in fig. 5A and 5B, the second display output region 1051 is made to be on the outside. The present invention is not limited to this, and the first display output region 1041 may be located on the outer side. By making the light transmittance of the second display output region 1051 equal to or greater than a predetermined value, only one of the first display output region 1041 and the second display output region 1051 is in display, and the display output region in non-display does not affect the display function of the display output region in display, thereby achieving a more compact configuration.

Fig. 5C and 5D are a top view and a side view, respectively, illustrating a second configuration example of a display output area of an electronic apparatus according to an embodiment of the present invention.

As shown in fig. 5C, the first display output region 1041 and the second display output region 1051 have a second configuration example adjacently disposed on the frame body 110 or the fixture 120. In fig. 5C and 5D, the first display output region 1041 and the second display output region 1051 are adjacently disposed in the frame body 110. The present invention is not limited thereto, the first display output region 1041 and the second display output region 1051 may be respectively at the frame body 110 and the fixing device 120, and a distance between the first display output region 1041 and the second display output region 1051 is less than a threshold value (such as 1 cm).

Fig. 5D further illustrates a side view of a second example configuration in which the first display output region 1041 and the second display output region 1051 have an adjacent arrangement. As shown in fig. 5D, the first display device 104 provided with the first display output region 1041 and the second display device 105 provided with the second display output region 1051 are disposed adjacent to each other as shown in fig. 5D, and the display directions of the first display output region 1041 and the second display output region 1051 are the same in the direction outward of the annular space or the approximate annular space.

Fig. 5E and 5F are a top view and a side view, respectively, illustrating a third configuration example of a display output area of an electronic apparatus according to an embodiment of the present invention.

As shown in fig. 5E, the first display output region 1041 and the second display output region 1051 have a third configuration example adjacently disposed on the frame body 110 or the fixture 120. Unlike the second configuration example shown in fig. 5C and 5D, as shown in fig. 5F, the display direction of one of the first display output region 1041 and the second display output region 1051 is in a direction outward of the annular space or the approximate annular space, and the display direction of the other of the first display output region 1041 and the second display output region 1051 is in a direction perpendicular to the direction outward of the annular space or the approximate annular space.

Next, an appearance effect example of the electronic device when the display output area as illustrated in fig. 5C and 5D is employed is described in detail with reference back to fig. 6.

As shown in fig. 6, the first display device 104 may be a general optical display system, and the first display output region 1041 may be a region corresponding to a first display screen of the first display device 104. Further, the second display device 105 may be a near-eye optical display system, and the second display output region 1051 may be at least a part of a surface of the second optical member 20 from which light rays exit, and the second display output region 1051 may be provided in the frame body 110.

It should be noted that although in fig. 6, both the second display module 10 and the second optical module 20 (including the collimating unit 21 and the waveguide unit 22) are disposed in the frame body 110, the present invention is not limited thereto. For example, the second optical assembly 20 may be disposed across the frame body 110 and the fixing device 120, and the second display assembly 10 may be disposed in the frame body 110.

In one embodiment, as illustrated in fig. 6, the size of the first display output region 1041 may be larger than the size of the second display output region 1051 due to the display principle of a normal display and a near-eye display. Therefore, when the distance between the viewer and the frame body is a first distance (for example, the first distance may have a relatively large distance value), the size of the first image presented in the first display effect in the first display output region 1041 viewed by the viewer is larger than the size of the second image presented in the second display output region 1051 perceived by the viewer in the second display effect.

The above phenomenon occurs due to the following reasons: when the viewer 30 is located at a specific position (a first distance at which the virtual image cannot be perceived) away from the electronic device 100 for viewing, the size of the first image presented with the first display effect in the first display output region 1041 as viewed by the viewer 30 is equal to the size of the first display output region 1041, and the second image presented with the second display effect in the second display output region 1051 as perceived by the viewer 30 is also approximately equal to the size of the second display output region 1051 because the virtual image cannot be formed as intended and only one light spot is generated.

In another embodiment, the first display device 104 may include a first display screen having a first size equal to the size of the first display output area. Meanwhile, the second display device 105 includes a second display screen having a second size smaller than the size of the second display output area.

Due to the display principle of the normal display and the near-eye display, when the distance between the viewer and the frame body is a second distance (for example, the second distance may have a closer distance value), the size of the first image presented in the first display output region in the first display effect as viewed by the viewer is equal to the size of the first display output region; and when the distance between the viewer and the frame body is the second distance (which is assumed to be a specific position where a virtual image can be perceived), a size of a second image presented in the second display output area in a second display effect as perceived by the viewer is larger than a size of the second display output area.

The above phenomenon occurs due to the following reasons: when the viewer 30 is located near a specific position (a second distance at which the virtual image can be perceived) of the electronic device 100 for viewing, the size of the first image presented in the first display output region 1041 with the first display effect as viewed by the viewer 30 is still equal to the size of the first display output region 1041, while the second image presented in the second display output region 1051 with the second display effect as perceived by the viewer 30 is larger than the size of the second display output region 1051 as forming an enlarged virtual image. Depending on the setting of the second display means 105, it may even be possible that the virtual image size of the second image as perceived by the viewer 30 as appearing in the second display output region 1051 in the second display effect may be several times, even several tens of times, larger than the real image size of the first image when the viewer 30 happens to be located at a specific location of the electronic device 100 for viewing.

As can be seen, in an electronic apparatus according to an embodiment of the present invention, a first display device may be configured to output a real image corresponding to a display image such that a viewer at a first distance from the electronic apparatus can view the real image in a first display output region, and a second display device may be configured to output a virtual image corresponding to the display image such that a viewer at a second distance from the electronic apparatus can perceive the virtual image in a second display output region, wherein a size of the viewed real image is equal to a size of the first display output region and a size of the perceived virtual image is greater than a size of the second display output region. Thus, the electronic device can provide a larger-sized and higher-resolution image or video display without being limited by the size of the wearable electronic device itself, such as a smart watch.

Next, a display switching method according to an embodiment of the present invention will be described with reference to fig. 7.

The display switching method illustrated in fig. 7 may be applied to the electronic device illustrated in fig. 1.

Hereinafter, still in a specific example in which the electronic apparatus is a wrist-worn electronic apparatus as illustrated in fig. 2, a display switching method according to an embodiment of the present invention is described in detail with reference to fig. 7. However, it should be noted that the present invention is not limited thereto. The electronic device may be any type of electronic device including, but not limited to: refer to a belt-mounted electronic device, a notebook computer, a tablet computer, a mobile phone, a multimedia player, a personal digital assistant, etc. The first display device and the second display device may be the same or different types of display devices. For example, one of the first display device and the second display device may be a normal display, and the other one is a near-eye display; alternatively, both may be common displays at the same time, or near-eye displays at the same time. Further, the display switching method according to the embodiment of the present invention can also be applied to any other process in the electronic device.

As illustrated in fig. 7, a display switching method according to an embodiment of the present invention may include:

in step S110, the first display device is turned on so that the first display device is in an operating state.

When a user needs to start using the electronic device 100 to perform a specific function (e.g., view time, make/receive phone calls, send/receive short messages, browse web pages, etc.), the first display apparatus 104 can be preferentially used because the general display has a large viewing angle, and does not need to perform operations such as position alignment during viewing, and is more convenient to use than a near-eye display.

In order to provide a graphical user interface for the user, in the electronic device 100, the processing means 103 may constantly generate display images and control the first display means 104 to constantly perform display.

However, since the electronic device 100 may be a portable electronic device (e.g., a wearable electronic device) that tends to need to be powered by an internal battery, and since the volume of the wearable electronic device determines where the capacity of the internal battery tends to be not high, continuously performing image display in the first display apparatus 104 will result in a severe reduction in standby time of the electronic device 100. Therefore, the electronic apparatus 100 is allowed to enter a standby state when the user is not operating, to save power consumption; and reactivates the electronic device 100 when operated by the user.

In order to determine whether the electronic device 100 needs to be activated from the standby state to the operating state, second parameter information related to a current input operation performed by the viewer may be obtained by the sensing device 106, and whether the current input operation is a second input operation is determined according to the second parameter information and a second determination result is obtained; when the second judgment result indicates that the current input operation is the second input operation, the first display device is turned on so that the first display device is in a working state.

In the first embodiment of the present invention, the above-described detection operation may be performed depending on different use gestures of the user for the electronic apparatus 100.

For example, it is first detected whether the current input operation performed by the user is a second input operation, which may be that the user moves the electronic apparatus 100 from another position to a first distance farther away from the user by driving his arm. Then, only when it is detected that the second input operation is performed by the user, the electronic apparatus 100 is switched from the standby state to the operating state.

Hereinafter, for ease of understanding, the description of the first embodiment will be continued with a wrist-worn electronic device (e.g., a smart watch) as an example of the electronic device 100.

Under normal use conditions of the wrist-worn electronic device, a user may wear the electronic device 100 on his wrist. This particular use posture determines the fact that the user can relax his arms so that the arms stick to one side of his body when the user does not need to use the electronic device 100 (it is needless to say that the user's arms may be in other positions if the user is not in a relaxed state but is performing other operations, for example, the user's arms are on both sides of his body and are continuously swinging while running); when the user needs to use the first display device 104 of the electronic apparatus 100, the user may lift the arm and turn over the limb (e.g., wrist) wearing the electronic apparatus 100, so that the electronic apparatus 100 approaches the user as a viewer, and maintain the first display output region 1041 at a first distance farther from the user in a parallel state or an approximately parallel state with the ground. For example, at the first distance, the user may view a real image corresponding to the first image from the first display output region 1041 of the first display device 104.

That is, when the user needs to start using the first display device 104 to complete a specific function (e.g., view time, make/receive phone calls, send/receive short messages, browse web pages, etc.), the user may first drive his/her arm to gradually move the electronic apparatus 100 from the body side to his/her chest until he/she is located at a first distance from the electronic apparatus 100, and then the user may view a corresponding user interface of the electronic apparatus 100 through the first display output area 1041 of the first display device 104 and control the electronic apparatus 100 through a specific input device (not shown, such as a touch screen, a stylus pen, a voice control, a body sensing control, etc.) to complete the specific function.

Therefore, it is possible to detect whether the input operation of the viewer with respect to the electronic apparatus is the second input operation based on the principle that the gravitational acceleration components thereof in the respective axis directions in the reference coordinate system (e.g., three-dimensional coordinate system) are different in different use states of the electronic apparatus 100.

Assume that an X axis, a Y axis, and a Z axis forming a three-dimensional coordinate system are set on the electronic device, where a plane formed by the X axis and the Y axis is parallel to a screen where the first display output region 1041 is located, and the Z axis is perpendicular to the screen where the first display output region 1041 is located. When the user holds the electronic device 100 such that the first display output region 1041 is placed perpendicular to the ground, the Y-axis is aligned with the direction of the gravitational acceleration G.

Specifically, when the user relaxes the arm on which the electronic apparatus 100 is worn, as described above, the electronic apparatus 100 inevitably slides down to the front of the user's wrist and is caught by the palm by gravity, so that the component of the gravitational acceleration G in the X axis is large and the components in the Y axis and the Z axis are small. Conversely, when the user views the first display device 104 of the electronic apparatus 100 as a smart watch, the user needs to lift the electronic apparatus 100 and flip the first display output region 1041 in the electronic apparatus 100 to a horizontal state and toward the user's eyes, so that the component of the gravitational acceleration G in the respective axes undergoes a series of changes to be finally fixed to be the largest in the Z-axis and smaller in the X-axis and the Y-axis.

To this end, the sensing means 106 may be first sensing means for obtaining spatial position information of the electronic device under control of an input operation performed by the viewer. At this time, depending on the above-mentioned usage posture of the electronic device under normal conditions, the above-mentioned detection function may be performed by determining whether the electronic device moves from an initial position (for example, an initial distance very far from the viewer) to a first position (for example, a first distance far from the viewer) in the gravity direction based on the spatial position information obtained by the sensing device 106, and determining whether the electronic device rotates from an initial angle (perpendicular to the ground, i.e., the X axis is directed to the gravity direction) to a first angle (parallel to the ground, i.e., the Z axis is opposite to the gravity direction) centering on the first manipulation body.

For example, the sensing device 106 may include a gyroscope or a gravity sensor disposed inside the electronic device 100. When the arm of the user is in a certain posture, the gyroscope or the gravity sensor may detect the gravitational acceleration component parameters of the electronic device 100 in the directions of the respective axes in the three-dimensional coordinate system, sense the angular acceleration component parameters generated by the user turning over the wrist, and determine whether the current input operation of the user is the second input operation by a combination of the two actions.

Further, in the second embodiment of the present invention, the electronic apparatus 100 in the standby state may be woken up by detecting that the user touches the activation area in the electronic apparatus 100, thereby turning on the first display device 104 so that the first display device 104 is in the operating state.

To this end, the sensing device 106 may be a second sensing device for sensing control operation information generated by a second operation body (e.g., a finger) of the viewer approaching or contacting a sensing area. The sensing region may include at least a portion of the first display output region 1041.

For example, the sensing device 106 may be a touch sensor. At this time, it may be determined whether the second operation body touches or approaches at least a portion of the first display output area according to control operation information (such as trajectory information, click information, proximity information, etc.) obtained according to the sensing device 106 to detect whether the user operates the activation area in the first display device 104 of the electronic apparatus.

Alternatively, in the third embodiment of the present invention, it is also possible to simply detect whether the input operation of the viewer with respect to the electronic apparatus is the second input operation based on the principle that the distance between the electronic apparatus 100 and the user is different in different use states.

Specifically, when the user does not use the electronic apparatus 100, the electronic apparatus 100 tends to be far from the eyes of the user, and thus, the distance between the electronic apparatus 100 and the user is very far. Conversely, when the user views the first display 104 of the electronic device 100 as a smart watch, the user needs to raise the electronic device 100 and flip the first display output region 1041 in the electronic device to a horizontal state and toward the user's eyes, so that the distance between the electronic device 100 (in particular, the first display output region 1041) and the user is relatively long, for example, the first distance.

To this end, the sensing device 106 may be a third sensing device for sensing a distance between the viewer and the electronic apparatus 100 (specifically, the frame body 110).

For example, the sensing device 106 may be a proximity sensor, which may detect a distance between the electronic device 100 and the user when the arm of the user is in a certain posture, and determine whether the input operation of the user is the second input operation according to whether the distance between the electronic device 100 and the user is equal to the first distance.

As shown in fig. 8, the proximity sensor may be disposed in the electronic device 100 at the same surface as the first display output region 1041 and in proximity to the first display output region 1041.

Furthermore, in other embodiments, the sensing device 106 may be a pressure sensor for detecting whether the user presses a power button provided in the electronic device 100. Alternatively, the sensing device 106 may be a voice sensor for detecting whether a user issues a voice command for turning on the first display device.

In step S120, a first image is presented in a first display output area by a first display device with a first display effect.

After the first display device 104 is switched to the operating state, the first image may be presented in a real image display manner in the first display output region 1041.

Specifically, when the viewer views the first display output region 1041 while holding the electronic apparatus 100 in front of himself or herself and keeping the vicinity of the first distance, the first image displayed may be a display interface including glanceable or summary information subject to size restriction since the first display device 104, which is smaller in size, tends to be provided in the electronic apparatus 100 as a wearable electronic apparatus.

For example, as shown in fig. 8, the first image may be summary information about time and weather forecast. Alternatively, when the electronic apparatus 100 is receiving an incoming call from a call originator, only the number of the incoming call, an icon of whether to answer the incoming call, or the like may be displayed in the first image.

In step S130, first parameter information related to a current input operation performed by a viewer is obtained through the sensing device.

Next, in order to enable the user to see a richer and more interesting display interface in the electronic device 100, the first display device 104 with a smaller output display area may be switched to the second display device 105 with a larger output display area automatically or manually by the user, so as to obtain a better user experience.

In order to determine whether the electronic device 100 needs to be switched from the first display apparatus 104 to the second display apparatus 105, first parameter information related to a current input operation performed by the viewer may be obtained through the sensing apparatus 106.

Similarly to in step S110, in the first embodiment of the present invention, the above-described detection operation may be performed depending on different use gestures of the electronic device 100 by the user.

For example, it is first detected whether a current input operation performed by the user is a first input operation, which may be a user moving the electronic apparatus 100 from a first distance farther away from himself to a second distance closer to himself by driving his arm. Then, only when it is detected that the first input operation is performed by the user, the display apparatus switching operation is performed.

In the following, the description of the first embodiment is continued with a wrist-worn electronic device (e.g., a smart watch) as an example of the electronic device 100.

Under normal use conditions of the wrist-worn electronic device, a user may wear the electronic device 100 on his wrist. This particular use posture determines the fact that when the user needs to use the second display device 105, based on the use posture using the first display device 104, the user can further lift the arm and flip the limb portion (e.g., wrist) wearing the electronic apparatus 100 so that the electronic apparatus 100 comes closer to the user as a viewer, and the second display output area 1051 is held at a second distance closer to the user in a perpendicular or approximately perpendicular state to the ground. For example, at the second distance, the user may view an enlarged virtual image corresponding to the display interface of the electronic apparatus 100 from the second display output region 1051 of the second display device 105.

That is, when the user needs to start using the second display device 105 to complete a specific function (e.g., view time, make/receive phone calls, send/receive short messages, browse web pages, etc.), the user may continue to drive his/her arm to gradually move the electronic apparatus 100 from his/her chest to his/her eyes until he/she is located at the second distance of the electronic apparatus 100, and then the user may view a corresponding user interface of the electronic apparatus 100 through the second display output area 1051 of the second display device 105 and control the electronic apparatus 100 through a specific input device (not shown, such as a touch screen, a stylus pen, a voice control, a body sensing control, etc.) to complete the specific function.

Therefore, it is also possible to detect whether the input operation of the viewer with respect to the electronic apparatus is the first input operation based on the principle that the gravitational acceleration components thereof in the respective axis directions in the reference coordinate system (e.g., three-dimensional coordinate system) are different in different use states of the electronic apparatus 100.

It is still assumed that an X axis, a Y axis, and a Z axis forming a three-dimensional coordinate system are provided on the electronic device, wherein a plane formed by the X axis and the Y axis is parallel to the screen where the first display output region 1041 is located, and the Z axis is perpendicular to the screen where the first display output region 1041 is located.

Specifically, when the user views the second display device 105 of the electronic apparatus 100 as a smart watch, the user needs to further raise the electronic apparatus 100, and turn the second display output area 1051 in the electronic apparatus 100 to the vertical state and aim at the eyes of the user, so that the distance between the electronic apparatus 100 (in particular, the second display output area 1051) and the user is close, for example, the second distance.

To this end, the sensing device 106 may be the first sensing device described above, such as a gyroscope or a gravity sensor or the like disposed inside the electronic device 100, for obtaining spatial position information of the electronic device under control of the input operation performed by the viewer. At this time, depending on the above-mentioned usage posture of the electronic device under normal conditions, the above-mentioned detection function may be performed by determining whether the electronic device moves from a first position (for example, a first distance farther from the viewer) to a second position (for example, a second distance closer to the viewer) in the gravity direction based on the spatial position information obtained by the sensing device 106, and determining whether the electronic device rotates from a first angle (parallel to the ground, i.e., the Z axis is opposite to the gravity direction) to a second angle (perpendicular to the ground, i.e., the Y axis is opposite to the gravity direction) centered on the first operation body.

Further, in the second embodiment of the present invention, switching from the first display apparatus 104 to the second display apparatus 105 can be performed by detecting that the user touches the activation region in the electronic apparatus 100.

For this purpose, the sensing device 106 may be the second sensing device, such as a touch sensor disposed inside the electronic device 100, for sensing the control operation information generated by the approach or contact of the second operation body (e.g., finger) of the viewer to the sensing area. Also, the sensing region may include at least a portion of the first display output region 1041 and at least a portion of the second display output region 1051.

At this time, it may be determined whether the second manipulation body slides from at least a portion of the first display output area to at least a portion of the second display output area according to control operation information (such as trajectory information, click information, proximity information, etc.) obtained by the sensing device 106 to detect whether the user manipulates an activation area in the second display device 105 of the electronic apparatus.

Alternatively, in the third embodiment of the present invention, it is also possible to detect whether the input operation of the viewer with respect to the electronic apparatus is the first input operation by detecting the distance between the electronic apparatus 100 and the user.

Specifically, when the user views the second display device 105 of the electronic apparatus 100 as a smart watch, the user needs to further raise the electronic apparatus 100 and turn the second display output area 1051 in the electronic apparatus to the vertical state and aim at the eyes of the user, so that the distance between the electronic apparatus 100 (especially, the second display output area 1051) and the user is close, for example, the second distance.

For this purpose, the sensing device 106 may be the above-mentioned third sensing device, such as a proximity sensor or the like provided inside the electronic apparatus 100, which may be shared with the proximity sensor on which the second input operation is detected; or may be a separate proximity sensor disposed in the electronic device 100 at the same surface as the second display output region 1051 and proximate to the second display output region 1051.

Further, in other embodiments, the sensing device 106 may be a voice sensor for detecting whether a user issues a voice command for switching from the first display device to the second display device.

In step S140, it is determined whether the current input operation is a first input operation according to the first parameter information and a first determination result is obtained.

After obtaining the first parameter information related to the current input operation performed by the viewer, it may be determined whether the current input operation performed by the user is the first input operation according to the first parameter information, that is, it is determined whether the viewer is present at the specific position (the second distance at which the virtual image can be perceived) of the electronic apparatus under the control of the first input operation performed by the user.

Since the specific judgment principle has been explained above with reference to the first to fourth embodiments in step S130, a detailed description thereof will be omitted.

If a positive determination result is obtained, the following step S150 may be performed. Conversely, if a negative determination result is obtained, it may return to step S130 to continue the detection operation.

Further, in one example, to save power consumption of the electronic apparatus 100, the power supply of the second display device 105 may be turned off when the second display device 105 is not used. Therefore, before step S150 is executed, when the first determination result indicates that the current input operation is the first input operation, the second display device may be turned on so that the second display device is in the operating state.

In another example, also in order to save power consumption of the electronic apparatus 100, a power saving operation may be performed with respect to the first display device 104 after switching the operating display device from the first display device 104 to the second display device 105. For example, the display output of the first display device may be controlled such that the first display device stops presenting the first image. Alternatively, the power supply of the first display device may be directly turned off.

In step S150, when the current input operation is the first input operation and the second display device is in the working state, a second image is presented in the second display output area by the second display device with a second display effect.

After the second display device 105 is switched to the operating state, the second image may be presented in a virtual image display manner in the second display output region 1051.

Specifically, when the viewer aims the second display output region 1051 at the eyes of the viewer while holding the electronic apparatus 100 in front of the eyes of the viewer and keeping it at the second distance, since the second display device 105 provided in the electronic apparatus 100 is a virtual image display device that presents a virtual image that is not limited to a small-sized screen as a wearable electronic apparatus, the displayed second image may be a display interface including detailed information.

A first image presented in a first display output area by a first display means in step S120 is illustrated in the left diagrams of fig. 9A to 9E, while a second image presented in a second display output area by a second display means in step S150 is illustrated in the right diagrams of fig. 9A to 9E.

Specifically, in fig. 9A, the left diagram presents brief information about the time display, including only time and air temperature; and the right picture presents detailed information about the time display including world time, world maps, city names, etc.

In FIG. 9B, the left diagram presents brief information about the information display, including only the amount of unread information and the contact name; and the right image presents detailed information about the display of the information, including contact avatars, contact names, and detailed content of the information (text and images), among others.

In FIG. 9C, the left diagram presents brief information about the navigation display, including only the direction indication; while the right image presents detailed information about the navigation display including maps, route plans, and location indications about the current location, the location of the next node, emphasis, etc.

In FIG. 9D, the left image presents brief information about the motion display, including only timing, kilometers, speed, heat consumption, direction; while the right image presents detailed information about the motion display including timing, kilometers, velocity histogram, map, motion trajectory, and indications about current and historical orientations, etc.

In fig. 9E, the left diagram presents brief information about icon display, including only the currently displayed image; and the right drawing presents detailed information about the icon display including time, air temperature, current icon, and list of adjacent icons, etc.

Therefore, in the embodiment of the present invention, it is possible to switch display contents by a near-far distance change in a normal display and a near-eye display by two juxtaposed adjacent screens. Further, it is also possible to switch display contents in the upper and lower screens by two overlapped screens (in which the upper screen is a transparent screen).

Such switching of display contents may be various.

In a first example, the switching of the display between the first image and the second image may be straightforward, e.g., the display of the first image may be turned off first and then the display of the second image turned on. Likewise, it is also possible to first turn on the display of the second image and then turn off the display of the first image. Alternatively, the display of the second image may also be turned on while the display of the first image is maintained.

In a second example, the viewing experience of the user may be improved by a dynamic switching effect between the first image and the second image.

For example, in the process from step S110 to step S150 described above, that is, in the process that the user can drive his/her arm to gradually move the electronic apparatus 100 from the body side to his/her chest and further from his/her chest to his/her eyes, the distance viewing effect can be made to transition naturally and achieve the continuity of the experience by the dynamic effect of the distance screen.

In one embodiment, presenting, by the second display device, the second image in the second display output region in accordance with the second display effect may include: controlling, when the distance between the viewer and the frame body is the second distance, display output of the second display device at a first timing so that a size of a second image presented in a second display effect in the second display output area perceived by the viewer is equal to a size of the first display output area; and when the distance between the viewer and the frame body is the second distance, controlling display output of the second display device at a second time after the first time so that a size of a third image presented in a second display effect in the second display output area as perceived by the viewer is larger than a size of the first display output area, wherein display content of the second image is identical to display content of the first image.

In this embodiment, the following display effects will be produced: that is, when the electronic device is positioned in front of the chest of the viewer, a first image including thumbnail information is displayed on the ordinary display, and when the electronic device is moved from the chest to the front of the eyes, a second image having the same size and content as the first image is displayed on the near-eye display, and then this second image is further enlarged on the near-eye display, and the second image is switched to a third image including detailed information, thereby obtaining a display effect in which the ordinary display seamlessly engages with the near-eye display.

In another embodiment, presenting, by the second display device, the second image in the second display output region in accordance with the second display effect may include: controlling display output of the first display device at a first timing so that a size of a first image presented in a first display effect in the first display output region as viewed by the viewer is equal to a size of the first display output region when a distance between the viewer and the frame body is a second distance; when the distance between the viewer and the frame body is the second distance, controlling display output of the first display device at a second time after the first time so that a size of a first image presented in a first display effect in the first display output area viewed by the viewer is smaller than a size of the first display output area; when the distance between the viewer and the frame body is the second distance, controlling display output of the second display device at a third time after the second time so that a size of a second image presented in a second display effect in the second display output area perceived by the viewer is smaller than a size of the first display output area; and when the distance between the viewer and the frame body is the second distance, controlling display output of the second display device at a fourth time after the third time so that a size of a third image presented in the second display output region by a second display effect perceived by the viewer is larger than a size of the first display output region, wherein the size of the second image perceived by the viewer at the third time is equal to a size of the first image viewed by the viewer at the second time, and display content of the second image is identical to display content of the first image.

In this embodiment, the following display effects will be produced: that is, when the electronic device is positioned in front of the chest of the viewer, a first image including thumbnail information is displayed on the general display, and when the electronic device is moved from the chest to the eyes, the first image is gradually reduced and finally changed into a second image (e.g., a circle, a square, a certain pattern, or even no display) of a small size, then a third image having the same size and content as the second image is displayed on the near-eye display, and then the third image is gradually enlarged on the near-eye display and finally changed into a fourth image including detailed information, thereby obtaining another display effect that the general display seamlessly engages with the near-eye display.

Obviously, the dynamic switching effect between the first image and the second image is not limited to the above two modes, as long as it can ensure that the interface animation of the ordinary display and the near-eye display keeps consistent at the moment from far to near from the side of the body to the chest to the front of the eyes. For example, in yet another embodiment, a first image displayed in a normal display is smaller, larger and faded out, while a second image displayed in a near-eye display is fading out, producing a near-to-far spatial effect, the content is also smaller, larger and faded in.

Therefore, with the display switching method according to the embodiment of the present invention, when it is currently detected that the viewer performs an input operation on the electronic device, parameter information related to the input operation can be obtained, and different display devices are turned on according to the parameter information, so that display images can be presented in corresponding display output areas according to different display effects through the different display devices according to different requirements of the user.
